SPECIFICATION formingpart of Letters Patent No. 717,380, dated December 30,1902.

Application filed September 8, 1902. Serial No. 122,562. (No model.)

ling-Machines or Similar Machines for Preparing Flax, Jute, and other. Fibers for Spinning, (for whichwe have applied for a British Patent,.No. 22,370, dated November 6,'l90l,

of which the following-is a specification.

Our said invention has for its object to provide improved and simpleymeans for carrying and actuating the gill-bars usedin drawing and roving frames or similar machines for preparing'flax, jute, and other fibers for spinning.

The invention is represented in the accompanying drawings, in which the same reference-letters are used to mark the same or like parts wherever they are repeated.

Figure 1 on Sheet 1 of the drawings is a transverse section of a drawing-frame provided with our improvements. Fig. 2 on Sheet 2 isla longitudinal section of the improvements as applied at one end of the frame or gill-bars.

In carrying out our invention a race or path A is formed on a plate A, fixed Within a head part B of the frame at each end of the machine in which the ends of the gill-bars work, so that these bars when actuated, as hereinafter described, can travel continuously, as usual, between the back or feeding rollers O and the front or drawing rollers .D, the race being fiat or horizontal on the top and curved or semicircular around the 0 bottom and sides. V

The followingimproved means are provided for actuating the gill-bars E. A wheel or carrier in the form of a ring Gis arranged at each end of themachine within the head part B, so as to encircle the end parts E of the gill-bars E, which bear on the race A, the innerperiphery ofthe ring being formed with teeth G,,which engage or gear with the gill-bars. The outer periphery of the ring G is also provided with teeth G which are sunk into the ring, so that their outer surfaces are race-plate A. Openings M idoor N,

-closed or secured b 'it might be a spring-latch.

H, loose on a driving-shaft J, a pin (not shown) being fixed to the sleeve, so as to engage Wiblltt driving connection on theshaft. Cranks K, fitted with crank-pins K, are fixed, preferably, to the opposite ends of each alternate gill-bar E, the pins sliding in a camgroove L, formed in a plate L, fixedjto the N are'provided in the back partition B of the framing-head B and the cover-plate Pinfrontof the wheel G, so as to enable the gill-bars E to beeasily gotat for removal when required, the'openingin the cover-plate being provided with a turning upward'on a hinge N and y an eccentric-lockN or On the machine being started the drivingshaft Jthrough its driving connection acts on the pin in'the sleeve H, s01 as to drive the sleeve andpinions H, and thereby rotate the toothed rings or carriers G, which then carry the gill-bars E around the race or path A as required. 7 The gill-bars E are turned on their axes in the course of their traveLso as to make the-gill-pins E enter and leave the fiber at'the proper angle, this turning movement being effected by the action of the suitablyshaped cams-groove L on the pins K in the cranks K on the ends of the gill-bars. A revolving brush R is provided, as usual, for cleaning the gill-pins E and the driving-pin in the sleeve H is made so that it will break in the event of the gill-bars E jamming, and damage to the machine is thus prevented. 9)

Our improvements, as hereinbefgre described, present many advantageous features, among which the following,which are oflimportance, may be named: The gill-bars E, for example, are effectively supported by the improved carriers G during't'ne course oftheir travel, so that friction is thus considerably lessened, and as the race A is of lesser perimeter than the carriers G a smaller number of gill-bars E is also required and they can 100 be driven at a higher velocity with less risk of jamming or damage. The arrangement of a separate driving-shaft J outside of the carriers G and gill-bars E is likewise extremely advantageous, as it makes each carrier independent of its neighbor, so that it is more easily driven, gives a steadier and smoother motion, and allows of greater ease in repairs and replacing the driving-pin in the pinionsleeve H in the event of that pin breaking.

What we claim as our invention is- 1. In hackling-machines in which gill-bars are used, a revolving annular Wheel or ring at each end of the machine, internal teeth in such wheels, which teeth engage with, support and carry the gill-bars, and a race or path for such gill-bars of lesser perimeter than the wheels or rings, substantially as herein set forth.

2. In hackling-machines, the combination of gill-bar-carrying rings or wheels and mechanism for driving same arranged outside of the said wheels and gill-bars, substantially as and for the-purposes herein set forth.

3. In hackling-machines, in which gill-bars are used, annular wheels or rings, ways or grooves provided in the framing at each end of the machine for said wheels, internal teeth in such wheels to engage with, support; and carry the gill-bars, gill-bars of lesser perimeter than the wheels or rings, external teeth on the wheels, pinions to gear with such external teeth, means for working said pinions from a driving-shaft outside the wheels and gill-bars, and doorways or openings in the parts of the framing into which the end portions of the gill-bars extend, substantially as and for the purposes herein set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
